Re: Help, broke down! - tbaxter08700 - 11-05-2013
Yeh still stage 2 and yep about 2 years...
So when I read with digimoto I just get the egr code same when I use obd2crazy???
RE: Help, broke down! - Poodle - 11-05-2013
Honestly dude, get some live data up on pp2k and see what she's doing when you're cranking, easiest way to narrow down your options. Know anyone local to you who can do it?
EDIT: IIRC you're a bit far from me, else i'd do it...
Re: Help, broke down! - tbaxter08700 - 11-05-2013
That the only program that can do it mate? Will ask about.
RE: Help, broke down! - Poodle - 11-05-2013
That and lexia 3 are your best bet, but any GOOD aftermarket scanner should do it - as in snap-on etc. Unfortunately they're all pretty expensive, figured pp2k was your best bet since quite a few members have it now.
Re: Help, broke down! - tbaxter08700 - 11-05-2013
Anyone know what this connection at the bottom is for? Seems to have a green wire missing? ?

RE: Help, broke down! - Toms306 - 11-05-2013
The one in the block? Oil pressure switch I think.
RE: Help, broke down! - DeeTurbo - 11-05-2013
That looks like the high pressure regulator. If there is a wire broken on that it will cause all sorts of problems.
Oops didn't see connector behind the regulator on my phone.
Re: Help, broke down! - tbaxter08700 - 11-05-2013
Just below the regulator, if you look Closely you can see there is a green wire sniped of of it?
RE: Help, broke down! - Jonny81191 - 11-05-2013
The one coming off the block has only one wire, there's a green plug that blanks off the spare.
Re: Help, broke down! - tbaxter08700 - 11-05-2013
Ok Cheers. No idea what to test now???
RE: Help, broke down! - Jonny81191 - 11-05-2013
Where are you?
Re: Help, broke down! - tbaxter08700 - 11-05-2013
Rotherham mate . South Yorkshire.
Re: Help, broke down! - tbaxter08700 - 12-05-2013
Jusy a quick one. Should the injectors measures 0 resistance? I read somewhere that if they do then there nakerd?
Edit
When I connect to the cables that go to the injectors they all measure about 5volts when I turn the key to glowplug posistion. Then it gradually goes down. This sound about right?
RE: Help, broke down! - Poodle - 12-05-2013
Seems odd if that's the case, never heard of that before, don't really know much about the electrics though.
The voltage when the glowplugs come on shouldn't be there i don't think, injectors receive a firing signal of 80v and not much else afaik. Should think it's interference/feedback from somewhere else, did you check to make sure all the earths are intact?

Dont understand the last part mate. I got the same voltage when I cranked it? Also I will have a check of the earth's.
RE: Help, broke down! - Poodle - 12-05-2013
Sorry, i meant the 5 volts you mentioned seeing on the injectors when you turn the ignition on - that shouldn't be like that afaik.
Injectors aren't receiving the firing signal then, so your ecu isn't willing to let the car start. Really need a look at that live data bud.
Re: Help, broke down! - tbaxter08700 - 12-05-2013
Got someone who can come down with pp2k but not till next week so until then just going to keep digging. I need my car lol
Any reason why it would show some voltage? Would of thought that it would be 80v or nothing?
This is how i am measuring the voltage going to the injectors.

RE: Help, broke down! - Poodle - 12-05-2013
Hmm, vid doesn't work.
I assume it would show voltage because of feedback/interference from something else, i don't know though. Need Cully in here lol.
Re: Help, broke down! - tbaxter08700 - 12-05-2013
Lol yeh could do with him. The vid should work mate it works on my phone in the browser.

Hes gone out to take pics of his '6! Hes got auto data too which would really help you work it out :/
Re: Help, broke down! - tbaxter08700 - 12-05-2013
Going to download autodata now. Dont know what to look for tho to be honest.
Re: Help, broke down! - tbaxter08700 - 12-05-2013
Just jad a thought. If the fpr is stuck or clogged would that stop the car from starting and also cause the low voltage to the injectors? Going to give it a clean just a bit stuck as the torx bolts are rounded off.
RE: Help, broke down! - Poodle - 12-05-2013
Just says stream not found or something.
You can check the frps to see if you've got enough fuel pressure, should show ~1.3v while cranking.
EDIT: The fpr could stop it starting, try the above to see if you've got pressure.
Re: Help, broke down! - tbaxter08700 - 12-05-2013
Getting really strange readings.will get a video up.if it does have the correct reading it could still be clogged tho couldn't it

RE: Help, broke down! - Poodle - 12-05-2013
Unlikely, the fpr controls the fuel pressure, if pressure is fine then the fpr is working. Hence checking voltage on the pressure sensor - that signal is the one the ecu uses, so if it reads fine you can rule out fuel pressure as the problem.
Re: Help, broke down! - tbaxter08700 - 12-05-2013
Sorry think I measured the wrong thing.did you mean measure the actual fpr or the connecter that goes on it?
RE: Help, broke down! - Poodle - 12-05-2013
Not the fpr, the frps - fuel rail pressure sensor.
Re: Help, broke down! - tbaxter08700 - 12-05-2013
Which one is that mate?
RE: Help, broke down! - Poodle - 12-05-2013
In the middle of the fuel rail, screwed in underneath with a red connector.
Re: Help, broke down! - tbaxter08700 - 12-05-2013
Oh right thats a pain to get to
